Double taxation after moving from Germany to UK

Hi team, I worked in Germany as an employee from July 2021 until June 2023, when I relocated to the UK to begin a new job. As I was tax resident in Germany as at June 2023, the German tax authorities required me to pay income tax for the entire tax year (January - December 2023), and I complied with this requirement. However, I also paid income tax to the UK authorities on the income I earned from my employment in the UK between June and December 2023. Consequently, I believe I have paid income tax on the same income to both the German and UK tax authorities for the period from June to December 2023. Could you please advise whether I am eligible to claim a refund for the double tax payments made to the UK authorities and, if so, how I should proceed? Thank you in advance for your assistance.

Hi,
You can see guidance here:

Thank you.

Not HMRC...appears you are statutorily resident for tax (SRT) in both countries for the year...Germany to Dec 23 and UK to April 24 in which case you need to establish which country is relevant for Treaty residence under the DTA. When you have decided which country you are Treaty resident in for that period you need to check the DTA to see who has the rights to tax that source for that period dependent on the article for employment income, and reclaim the tax from the other. Am assuming you are completing SA returns...you should be, to claim split year (if appropriate) on return to UK, otherwise HMRC can tax the period prior to return also...which would mean residence pages need to be completed
